All need to verify if a K frame that came with a duster I bought is a big block k frame. I bought a 73 duster that was a 340 car and had had a big block in it. Seller said it had a big block k frame and an extra small block k frame was with it. I think he had it backwards. The k frame in the car was the factory small block spool mount k frame with big block spool mounts to run the big block. The extra k frame said 74 duster 340 on it but it was a 72 and earlier biscuit style unlike my small block k frames from other a bodies of that era and judging from other pics isn’t a slant 6 k frame either... it looks like a big block a body k frame but I am not a big block a body expert. What do you think? Will be looking to sell this and some other stuff that came with the car I won’t be using to help fund the build at some point. Thanks in advance for the help.
